GRE G10 with ptfe energized seal / ASME B16.201

The gasket material incorporates high strength, glass reinforced epoxy laminated bonded to a stainless steel core. This provides the strength of a traditional metallic gasket while maintaining complete electrical insulation between the flange faces. Seal grooves are machined through the laminate insulating material and into the stainless steel core which provides a strong base for the seal to seat into and breaks the potential leak path that is inherent in glass laminate materials. Spring-energized PTFE internal face seals are installed in the dovetail shape seal grooves to provide the reliable sealing.
